Just to clarify, the vuln was not mentioned on HN, just the new about it being
under a free license. Then I did a git clone, and grep /tmp and pointed on internal 
IRC that, as usual, there is a ton of /tmp issue (and then Kurt did see and asked where I did see it,
and answered on HN (to the question "bk is now opensource").

for example:
https://github.com/bitkeeper-scm/bitkeeper/blob/master/src/utils/bk_version#L1563 

There is also a few here:
https://github.com/bitkeeper-scm/bitkeeper/blob/master/src/utils/extractor.c

but that's the installation script, so unlikely to be exploitable.

Or in apply-patch, etc.

But there is also a few projects that are bundled (like zlib), and a few scripts that
are used only at installation and/or build time, so classifying everything is more 
work than what I have time to devote for the project.
